Dammit. At first I thought it was just the copy of Katamari Damacy I recently got in trade, but now it's doing it with Okami, too.
I was playing a PS1 game a bit ago (Tekken 3 GH), then I turned off the PS2 for a bit, got Okami, put it in the system, turned it on, and the music during the intro was kinda skipping. It sounded like someone was pushing the mute button repeatedly.
I'm not sure what is causing this... what can I do?
